Flue beader

UNITED STATES LESTER M. ZEA', OF LA HOG-UE, ILLINOIS FLUE BEADER.

Application filed April 17, 1922. Serial No. 554,334.

To all whom it may concern:

Be it known that I, LESTER l1. ZEA, a citizen of the United States, residing at La Hogue, in the county of Iroquois and State of Illinois, have invented new and useful Improvements in Flue Beaders, of which the following is a specification.

This invention relates to flue headers, and an object of the invention is to provide a device by means of which the beads may be quickly and accurately turned on the ends of boiler flues for sealing the fiues to the boiler plates and locking the beads in place.

More, specifically, the invention comprises the provision of a body tube adapted for engagement into the end of the boiler tube, in which body tube is slidably mounted for limited movement a boiler flue engaging member, adapted to be struck by a hammer for forming the bead on the boiler tube or flue, which member is urged into engagement with the end of the boiler flue by means of the spiral spring.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawings wherein:

Figure 1 is a longitudinal section through the improved beader showing its application.

Fig. 2 is a top plan of the improved header.

Fig. 3 is a top plan of the beading or movable member.

Fig. 4 is a slide elevation of the header showing a slight modification thereof.

Fig. 5 is a transverse section on the line 5-5 of Fig. 4:.

Referring more particularly to the drawings, the improved beader comprises a tubular body 1 one end of which is closed by a closure plug 2 which is securely riveted or otherwise suitably attached to the body 1 as clearly shown in the drawings. The plug 2 is provided with a central opening 3 through which the stem 4: of the boiler flue engaging member 5projects. The boiler flue engaging member extends longitudinally in the body 1 and is provided with a slot 6 extending longitudinally therein through which a guide pin 7 is inserted. A spiral spring 8 is coiled about the member 5 and engages the guide pin 7 at one end and a pin 9 at its opposite end as clearly shownin Fig. 1 of the drawings. The spiral spring 8 acts to urge the beading surfaces 10 of the anvil 11 of the member 5 out of engagement with the end of the boiler flue as indicated at B. The anvil 11 projects through a longitudinal slot 12 formed in the body 1 at its end remote from the plug 2, which slot opens out through the end of the body 1. The member 5 is provided with a longitudinally extending projection 13 extending outwardly from the anvil 11 and having its upper surface rounded as shown at 14 to conform to the curvature of the body 1, the

upper surface of said extension merging into the arcuate bead forming edge 10 of the anvil, and the extension is provided for properly guiding movement of the member 5 in cooperation with the pin 7 duringthe bead forming operation thereof.

In forming a bead upon a flue boiler as shown at B the tool or header is placed so that the arcuate bead forming edge 10 of the anvil 11 will engage the outer end of the flue A which is at such time straight as shown at the lower portion of Fig. 1 of the drawings. After the bead is thus placed the stem 4 is struck a sharp blow with a hammer or similar tool which will drive the member 5 inwardly causing the anvil 11 to form the bead as indicated at B in Fig. 1 of the drawings. Auxiliary sleeves 15 are provided which may be mounted upon the slotted end of the tubular body 1 for increasing the diameter thereof to cause the tube to properly fit any boiler flues A which have greater diameters than the diameter of the body tube 1, and these auxiliary sleeves may be attached to the body tube 1 by a bolt such as indicated at 16 in Fig. 5 of the drawings.

'If it is so desired, the outer surfaces of the body tube 1 may be roughened as indicated at 17 to facilitate a firm gripping of the bead during operation. It will be apparent that only a portion of the complete bead B will be formed upon the flue A upon each blow struck against the member 5 and to complete the head it is necessary to rotate 1. In a beader, a tubular body, a closure plug in one end of said body, a bead forming member slidably mounted Within said body and provided With a longitudinally extending slot, a guide pin carried by said tub ular body and projecting through said slot, a transverse pin carried by said member, a spiral spring carried by said member and engaging said transverse and guide pins, and a bead forming anvil formed upon said t member.

2. A header comprising a tubular body, a

bead forming member slidably mounted Within the body With one end projecting beyond said tubular body and formed with a slot, a pin mounted in the body and Within the slot, and a spring mounted to force the bead forming member in a predetermined direction and entirely enclosed Within the body.

In testimony whereof I affix my signature.

LESTER M. ZEA.
